I ordered tickets online, so it could be quick, easy, and paperless. I was charged a $10 service fee, I was wondering what the charge is for?

Processing fee.. pretty common for movie tickets online

It's a processing fee

It's a online fee. They have always charged a online fee.

There's always an extra fee when you order online.

It's just a mandatory fee they add to every purchase. It's not really "for" anything except extra profit for Disney.
